The-obj ect, of my invention is to provide an .imprjovedconstruction and arrangement whereby the said guard is reversible, thereby to permit use thereof-on either sideofthe blade.

Anothersobject is to provide an improved construction and arrangement whereby the uard is. held securely in. place at the outer end of the blade, andwhe'reby, with a twoedged blade having .adbngitudinal ridge extending. midway between ;the two edges, it

will not .be necessary. to use; devices heretofore considered. necessary for ,Jholding the guard against lateral displacement.

Another object is toiprovide;animproved construction. and arrangementywhereby the guard ;is* held more. firmly and. securely against endwise displacement from theblade.

To; these .and other- .useful Tends, my invention consists. in matters hereinafter set forth and claimed.

the blade that is to say, theblade is hollow-ground on each side thereof, and lthe two shallow and longitudinal grooves thus "formed on each surface of the. blade provide the said ridge between them. At its outer end, @the said blade isprovfided on either side thereof with a transverse depression or cross-groove 2, formed in any suitable manner, so that the blade is thickerta't the end than between the bottoms ofthe two depressions.

' pivoted at (Z to the tang or shank of the blade, so that the razor blade and its guard will fold within said handle, in the manner of an ordinary razor. Thus the razor can be used either with or without the guard, and the latter can be used on either side of the blade. Without the guard, the blade and handle form a complete ordinary razor.

By ordinary, I mean the old and common and a handle at one end thereof.

form of razor having a solid or thick blade The blade A, as shown, and as described, has the same formation on both sides thereof, being what is ordinarily known as a hollow-ground blade, so that in cross-section each side has two "concave curves. The guard B, therefore, in crosssection, has two convex curves to fit the concave curves of the blade,so that the guard is held by either ridge 1 against lateral displacement, but is at the same time removable from the blade I by slight outward endwise movement thereof away from the handle. When the guard is forcibly moved endwise, away from the handle, the flexible lug d rises out of the depression 2 (at either side of the blade),

- thus permitting complete detachment of the on each side to provide two ridges and havguard from the blade. i

What I claim as my invention is:' g 1. Atwo-edged razorblade hollow-ground ing an integral shank at one end thereof, a handle secured to said shank, so that said blade and handle can be used as an ordinary two-edged razor, and a two-edged guard which in cross-section has two convex curves to fit the concave curves of either side of said blade, so that either ridge will hold the guard against lateral displacement, and which guard is attachable directly to opposite ends of said blade at either side thereof to convert said ordinary razor into a twoedged safety razor having said guard reversible from one side of the blade to the other, said guard being detachable by endwise movement for a short portion of the length thereof in direct contact with either side of the blade. I

2. A two-edged razor blade having an integral shank, a handle secured to said shank,

28th day of ridges, a lug on said guard to engage in either'of said depressions, and an extension on said guard to engage said means at either side of said shank, said lug being held against lateral displacement in said depressions by the adjacent engagement of said ridges with said guard.

Y 3. A two-edged razor-blade having an integral shank, a handle secured to said shank, so that said blade and handle can be used as an ordinary two-edged razor, a two-edged guard which is attachable directly to opposite ends of saidblade to convert said ordinary razor into a two-edged safety-razor, said blade havingjits end provided with a transverse depression, said'shank having ex ternal attachingmeans, the middle portion of said blade being thickened to'form a longitudinal ridge, said gnard being formed to fit said ridge, a lug on said guard to extend over the blade and engage in said depression, said lug being flexible to rise out of said depression when said guard isforciblymoved endwise from the blade, and an extension of said guard to engage said means on the shank, said deprcssionbeing so formed that said lug is movable sidewise but held against lateral displacement'therein by the engagement of said ridge with said guard.

4. A two-edged razor blade having an integral shank, a handle secured to said shank, so that said blade and handle can be used as an ordinary two-edged razor, and a two-edged I guard which is attachable to opposite ends 'of said blade to'eonvert said ordinary razor into a two-edged safety razor, said blade having a depression at the outer end thereof, and'said guard having a resilient lug disposed in position to lift slightly as the end ofthe blade is inserted thereunder and to then spring into said depression, so that the guard is held by said lug against endwise displacement from the blade, and said lug being fiexibleto rise out of said depression when the guard is forcibly moved endwise from the'blade. I

5. A razor blade having its outer end portion formed with depressions at opposite sides thereof, so that the blade is thicker at the end than between'the bottoms of said depressions, and a guard having its outer end providedv with oppositely arranged portions to enter said depressions, one of said portions being a resilient lug adapted to lift slightly as the endof the blade is inserted between the two portions'and to'then spring into the depression, and said lug being flexible to. rise out of said depression when the guard is forcibly moved endwise from the blade.
